[Bug 399559] [NEW] ATI Radeon Mobility KMS modeset=1 22% slower than vesa

 

Public bug reported:

Binary package hint: xorg

The bug is KMS modeset=1 measured 22% slower than vesa with video
intensive GtkPerf is from Ubuntu synaptic, and 12% slower than
modeset=0.  At least for this benchmark ubuntu is faster with vesa than
with the specific ati drivers.

Does anyone know how to get launchpad to handle columnar data?  
There are 5 columns of data here.

Measurements are from IBM Thinkpad T40 with ATI Radeon Mobility 7500.
Col 1 is measurements with xorg driver vesa.
Col 2 is nomodeset no KMS xorg ati driver 6.12.99+git.....
Col 3 is modeset=1 KMS xorg ati driver 6.12.99+git.....
